In order for the girlfriend not to have any claim on the house, it is essential that she pays nothing whatsoever except food although even that is an indirect contribution.
A cohabitation agreement is absolutely essential whereby she agrees that she moves into the property, doesn’t contribute towards it, but then again has no claim on it, and it is also essential that she takes legal advice on the effect of the agreement. It’s not sufficient to say that she has been advised to take legal advice and doesn’t want to, she must take that advice and must get it in writing and it must be from a high street solicitor. It would not be sufficient for that advice to come from this website, even though the advice would ultimately be the same.
The potential problem is that she has a child and if she refuses to move out, courts are reluctant to make children homeless so although she may not have a financial claim on the property, if he has been treating the child as a child of the relationship, he can end up being stuck with it.
