Pre-nuptial or pre-marital agreements

A pre-nuptial or pre-marital agreement (also commonly referred to as a ‘pre-nup’) will map out how your finances will be divided in the event of a separation. They can also include practical arrangements, providing financial security at the same time as reducing the stress, uncertainty, and cost of having to unravel your affairs should the worst happen.

Post-nuptial agreements

A post-nuptial agreement (also commonly referred to as a ‘post-nup’) is entered into after marriage.  These can be used if there has been a change of circumstance after marriage, for example receipt of an inheritance or other significant financial change.  They can also be used if there hasn’t been enough time before the marriage to complete a pre-nup.

Our clients are our best advocates on the benefit of having a nuptial agreement

“We always felt that a pre-nuptial agreement was a sensible option, and, while not a very romantic task to complete in the lead up to the wedding, we did feel that going through complete financial disclosure with each other and agreeing on what we did and didn’t want out of the agreement put us in good stead for our marriage moving forward. Should anything go wrong, we also think that having the agreement in place should reduce the stress, uncertainty and legal costs related to any divorce proceedings. And we felt this was important, particularly if children are involved. I would recommend this service”.

Guide to pre and post nuptial agreements

A nuptial agreement cannot stop a financial claim being made to the court on marriage breakdown, however, if a claim is made the nuptial agreement will be a relevant circumstance.  Provided the three-stage test in the case of Radmacher v Granatino has been complied with the agreement will be given decisive weight and parties should expect the court to hold them to the terms of the agreement. In Radmacher v Granatino [2010 UKSC 42] the Supreme Court enforced a pre-nuptial agreement and confirmed that ‘the court should give effect to a nuptial agreement that is freely entered into by each party with a full appreciation of its implications unless in the circumstances prevailing it would not be fair to hold the parties to their agreement’.
If there is no nuptial agreement in place, a principle of equal sharing will apply as the starting point to all assets, regardless of their source. A nuptial agreement can ensure that the interests of the wider family are safeguarded, particularly if family businesses, trusts or inherited assets are involved. As well as protecting assets, these agreements also allow you the freedom to plan what will happen to your finances, rather than leaving it to chance for a court to decide. They also provide a level of clarity and certainty for any children or dependants.
We understand discussing a pre-nuptial agreement can seem rather unromantic at a time when you are in love and planning your wedding. We also understand that there may be pressure on you from wider family members. Having helped hundreds of clients separate we know that the stress, uncertainty, and legal costs for couples without a nuptial agreement are significantly higher than those couples with agreements in place.
