Who our family law solicitors can help

Our family law solicitors can help when a claim arises. For example:

  • In divorce proceedings: if you have an interest in assets that are set to be divided between the separating couple, for example a share of a property or business
  • In cohabitation disputes: if you have a stake in the property or finances involved in a dispute between an unmarried couple

Who may wish to intervene in divorce financial remedy proceedings?

Examples of who may intervene in divorce financial remedy proceedings include:

  • Business partners: who may also be siblings or other family members of a person getting divorced and may wish to protect the business assets by defining the extent of the divorcing spouse’s interest.
  • Trustees: where a spouse is the beneficiary of a trust, the trustees may have a duty to the other beneficiaries. They might claim to ensure that all entitlements are taken into account when deciding what may be available to the divorcing beneficiary.
  • A parent: where the divorcing spouses have previously agreed to accommodate a parent or look after them in the family home but this will not be possible following divorce, the parent may have a claim for their interest to be taken into account.

How our solicitors can help with third party claims

Divorce financial settlements involving a third party

Our expert divorce solicitors have particular experience in complex divorce financial settlements where a third-party may have an interest in the assets being split between you and your ex-spouse. For example, parents who provided a loan to purchase the family home or a family farm where relatives may have an interest in the marital home and the running of the business.

Whether you need to challenge a third party’s interest in your divorce or support it, getting expert legal advice early can help secure a favourable outcome.

Protecting your financial interests in someone else’s divorce

Where a couple are divorcing and dividing their finances, there are often issues in determining what assets they hold and what they are worth. If you have an interest in those assets, as a parent or business partner for example, you may want to bring a third party claim to protect your position.

In these situations, one of the separating parties often challenges or denies your interest and wants the whole asset to be available for division on separation. This means that you will have to defend your interest by intervening in the divorce proceedings. The Court will then need to determine the extent of your interest in a separate procedure before it can resolve the financial claims between the spouses.

It’s important that you receive prompt expert advice in these situations to ensure that your interests are adequately recognised and protected. We have specialist experience in dealing with this complex procedure and can guide you through it with diligence and care.

Frequently asked questions on business prenups

A third party, often referred to as an intervenor, is someone who’s not one of the separating parties, who claims to have an interest in assets involved in the divorce or dispute. This can include parents, trustees or business partners whose financial interests could be affected by the outcome.

Intervention is usually considered where the disputed asset or assets are said to belong, in whole or in part, to someone outside the marriage. Getting legal advice early is important, particularly if your interest is being challenged or overlooked as part of the financial settlement.

If a third party does not intervene, the Court may proceed on the assumption that the assets are available for division between the separating couple. This can make it harder to protect your interest later. Our solicitors can advise you on whether intervention is necessary to safeguard your position.

The Court will consider evidence such as ownership documents, financial contributions, loan arrangements and the parties’ intentions at the time the asset was acquired. Our solicitors help third parties clearly explain and protect their financial interests during a divorce or dispute involving property, business assets or loans.

Yes, third party claims frequently arise where family businesses, property, trusts or loans from relatives are involved. These situations can be particularly sensitive, combining legal, commercial and personal considerations. Our solicitors are experienced in handling these complex dynamics, often involving many different areas of legal expertise.

In some situations, negotiation or mediation may resolve issues without the need for a full Court determination. Our solicitors explore proportionate solutions wherever possible, while remaining prepared to pursue or defend claims through the Court if required.
