When should we sign up to a Cohabitation Agreement?
There is no set rule as to when you should enter into an Agreement.
However it is advisable that if you intend to purchase a property jointly that you have the Agreement in place at the time of or prior to completion of your purchase.
It is better to have an Agreement clearly recording the intentions of both of you at the outset.
However the Agreement can be signed even after cohabitation has begun though of course there may be less compulsion for that to happen once you are safely ensconced in your new home!
Whilst timing is therefore not critical (though it is always preferable) it is more important to ensure that the Agreement is not signed at a time when either party might suggest that they were in a vulnerable position which was somehow exploited by the other party exerting undue pressure.
The effect of this could be to render the Agreement voidable.
