Called to the Bar in 2001, Mark is a highly experienced family barrister, based in the North West.
Finance and Property
Mark’s money practice ranges from 'needs cases' with modest capital, to those involving high net worth individuals often with assets abroad, off-shore, or (allegedly) hidden. He attends hearings throughout England and Wales including those allocated to Lead Financial Judges, and specialist TOLATA judges. He is regularly instructed by solicitors and via direct access. He has been instructed to appear against King’s Counsel.
Mark’s financial remedies work typically involves claims for the sale of the family home or other (e.g. investment) properties, applications to share (or attempts to ‘ring-fence’) pension pots, claims for spousal and/or child maintenance (outside the CMS regime), and claims involving third party Intervenors, such as wider family members. He is experienced in cases where parties have sought to uphold or depart from pre-nuptial agreements, separation agreements or consent orders.
While the usual TOLATA case involves separating, unmarried partners, Mark has acted in cases of parent -v- son/daughter, claims between siblings, and a claim between a divorced couple who had both remarried. He is familiar with Schedule 1 applications to counter a trusts claim, and the interplay between the two regimes.
Mark acts at all stages from advising pre-issue, through FDR and final hearing to appeals, enforcement and variation applications. He is conscious of costs at every stage and will explore settlement wherever possible. Where a final hearing is inevitable, he is known to be forthright in cross-examination and submissions should that be required.
Mark helps parents (and on occasion other family members) facing difficult disputes over child arrangements, contact, specific issues and prohibited steps, and parental responsibility. He is experienced in cases between parents with local authority involvement, as well as allegations of domestic abuse and substance abuse. He has acted in numerous applications to relocate within the jurisdiction and for permission to relocate abroad.

Fees and Feedback
Details regarding our approach to fees can be found at the following link: http://www.clerksroom.com/content-html?cid=514
Please see “profile” tab for a description of the legal services provided by this barrister.
We aim to complete and return all paperwork within 14 days (2 weeks) of receipt if no specific deadline is provided. We can work to much faster timescales if requested or we can agree a specific target date for each individual circumstance. We will always advise at the outset if counsel is unable to meet any deadline.
Each barrister has a standard hourly rate for their work. The individual hourly rate can be agreed when instructions are acknowledged if preferred. We welcome early discussion as to the suitability of a specific barrister for a specific case. The right barrister will have the relevant expertise to deal with the case but will not be too junior, or too senior depending on the complexities.
We aim to allocate all cases to the correct level of experience & seniority which we believe will prove most to be the most cost-effective solution for our clients.
If, due to urgency, we allocate paperwork to a more senior member of Clerksroom, we will charge the appropriate hourly rate for the work, not for the barrister. We welcome early discussion to ensure the correct fee is applied to the case at the outset.

1. This is a privacy notice that describes how, why and for how long I will process or keep your personal data in accordance with the General Data Protection Regulation (‘GDPR’).
2. The GDPR governs how an individual’s personal data is used, and your rights in relation to that data.
3. I, Mark O'Callaghan, have been instructed by you or your litigation friend (usually a parent), through your solicitor or agent, or via the Bar Pro Bono Unit.
4. It is necessary for me to process your personal data in order for me to provide you with legal services, for example:
· Advise on the prospects of litigation;
· Advise on the value of your claim;
· Representation at a court hearing;
· Representation at trial;
· Advise, review or comment on legal issues or evidence.
5. Processing means anything done to data such as: recording, organising, adapting, altering, copying, consulting, transmitting, combining, erasing or storing it.
6. The processing for the purposes listed above will take place in accordance with either Article 6(1)(a) GDPR or Article 6(1)(b) GDPR, depending on how you instructed me.
7. If you have instructed me on a direct access basis, or engaged a solicitor (or legal agent), to assist you in bringing or defending a claim then the processing is necessary to perform a contract to which you are a party (Article 6(1)(b) GDPR). To give effect to that contract (i.e. to bring a claim) it is necessary for me to process your personal data for litigation purposes.
8. If I am assisting you on a pro bono basis, it will be necessary for me to seek your consent to be able to represent you (Article 6(1)(a) GDPR). In this scenario, you will be sent a consent form.
Recipients of your data
9. I may also be required to share your data with others, depending on the nature of your case. This may include:
(i) Courts and other tribunals to whom documents are presented;
(ii) Your solicitors, or agent representing you, through whom I have been instructed;
(iii) Potential witnesses, experts and other persons involved in the case;
(iv) Solicitors, barristers, or other legal representatives;
(v) Ombudsman and regulatory authorities;
(vi) Education and examining bodies; and
(vii) Current, past or prospective employers.
Special Categories of Data
10. In some cases I will have been given your personal data that is within the ‘special categories’ of data described in GDPR Article 9(1). For example, personal data that reveals your race, ethnicity, sexual preferences, political or religious beliefs, trade union membership or health. There are also restrictions for processing information regarding criminal convictions.
11. This type of personal data will only be processed where it is necessary in order to represent you in your legal claim, or advise on the prospects of a legal claim.
12. I will retain your personal data for no longer than is necessary, and where it is possible, I will anonymise your data.
13. How long your personal data is kept will depend on a number of factors. The retention period will be reviewed when the service I am providing you with is complete. However in general, I am obliged by the Bar Code of Conduct to retain records of my cases, and by HM Revenue and Customs to retain records for 6 years.
14. Once your case has concluded and fees have been paid, I shall retain only the personal data necessary for the following purposes:
(i) The legal and professional obligation to retain information relating to my cases;
(ii) To check for any potential conflict of interests that may arise in the future when I am instructed on other cases;
(iii) For use in the defence of potential complaints, legal proceedings or fee disputes;
(iv) To refer back to in future cases which raise similar legal, factual, or procedural issues.
15. The processing for the purposes listed in paragraph 14 (ii), (iii), and (iv) above, will take place in accordance with Article 6(1)(f) GDPR. That is, for the purposes of legitimate interests that are not outweighed by your interests or fundamental rights and freedoms.
16. The processing for the purposes listed in paragraph 14(i) above, will take place in accordance with Article 6(1)(c) GDPR. That is, the processing is necessary for me to comply with a legal obligation.
17. Where processing of your personal data was based on your consent (see paragraphs 6 and 8) you have the right to withdraw that consent at any time. This does not affect the lawfulness of the processing based on consent before its withdrawal.
18. Withdrawal of your consent to process such data will most likely mean that I am no longer able to provide you with the legal services you seek.
19. You may request confirmation that your personal data is being processed by me and details about the personal data, the source, the processing, the purposes of the processing, the recipients and the retention period.
20. You may request a copy of your personal data that is being processed by me. You may also request rectification (i.e. correction) where there are inaccuracies in the personal data.
21. You have the right to object, on grounds relating to your particular situation, at any time, to processing of your personal data in paragraph 14 of this privacy notice. Should you object, the processing will only continue where there are compelling legitimate grounds for the processing which override your fundamental rights, freedoms and interests.
22. Where the processing or retention of your data is necessary for the establishment, exercise or defence of legal claims, it will not be possible to object.
23. You have the right to request that your personal data is erased where any of the following apply:
(i) The personal data are no longer necessary in relation to the purposes for which they were collected or otherwise processed;
(ii) You withdraw your consent where the basis of processing was based on consent and where there is no other ground for the processing;
(iii) Where your fundamental rights, freedoms and interests override the legitimate interests of processing in paragraph 14;
(iv) The personal data has been unlawfully processed; or
(v) The personal data have to be erased to comply with a legal obligation.
24. You have the right to request that your personal data is restricted from processing, so that it is simply stored, for the following reasons: as an alternative to deletion; so that it can be corrected; for the establishment, exercise or defence of legal claims; to verify if a legitimate ground exists (paragraph 14).
25. Where it is necessary to correct your personal data, or you have requested the restriction or erasure of your personal data, I shall endeavour to contact the recipients of the personal data, unless this involves disproportionate effort.
26. I take appropriate physical and technical procedures to safeguard your personal data to prevent it from being accidentally lost, used or accessed in an unauthorised way. The I.T. systems used by Clerksroom are ISO27001 compliant.

Mark O'Callaghan recently assisted me in a two-day variation hearing [in respect of a financial remedies order]. It wasn’t the easiest of matters but his calm and collected nature helped to keep my anxiety in check. Many thanks and would definitely recommend.
Alexander Adeyemo Alfred James Solicitors
It has been a pleasure to work with you and further briefs on the way in future. The client was similarly very pleased with your calm approach and the outcome was added positive feedback.
CL Direct Access Client
A Barrister with considerable experience, Mark achieved the result that I wanted [at an FDR appointment] and actually managed to improve the outcome. I appreciated the time taken to get to know the case before the day, which played a part in the successful outcome. Mark worked his socks off on the day from the moment he arrived to get the parties to reach agreement. I was stunned and delighted with the outcome.
M Woodcock Direct Access Client
Mark was able to quickly and efficiently understand my [financial remedies] case, whilst managing my personal expectations where others had lacked composure to do so. What sets Mark apart from other Barristers is his personal tone in a very confusing and stressful arena. He was able to pitch my case with absolute balance and clarity ... I had complete trust Mark was able to convey my opening statements to the judge with persuasion and influence. A quality operator."
