What is a Postnuptial Agreement?

A post-nuptial agreement or “postnup”, is an agreement entered into after a marriage or civil partnership which sets out what the financial terms of any separation, divorce or dissolution would be.

It can be useful to enter into one of these agreements if your circumstances have changed since signing a pre-nuptial agreement, for example, if one of you has received an unexpected inheritance since the marriage or you have had children or acquired property. Alternatively, you may wish to enter a post-nuptial agreement if you ran out of time to sign a pre-nuptial one (pre-nuptial agreements must be signed no later than 28 days before the marriage). If you amend a pre-nuptial agreement after the marriage, it becomes a post-nuptial agreement.

Occasionally, a couple may wish to sign a post-nuptial agreement if the marriage has previously been in difficulties and they wish the relationship to continue but with clarity over their finances.
