Signing a Tenancy Agreement. Should I?

I echo what other posters have written.

I am also very sorry for you with regard to your other daughter.

Don't be browbeaten into doing anything you don't want to do. Make things watertight.

I would advise the same,see a solicitor and get everything legal and on paper .Dont sign anything over until you're sure its what you want to do .They'll get it after you've gone anyway.Dont let them intimidate you to get their own way.Good luck with it ,hope it goes well for you

I'm sorry you are in such as difficult situation, especially as you must still be grieving.

As you own the house and they will be paying you rent, it seems to me that some sort of formal agreement is needed to protect both sides.

I suggest you get advice from a solicitor (free initial consultation, maybe?) or Citizens Advice. If you do sign over their share, make sure that you are protected. If I remember rightly, when we shared a house with my parents we were advised to own it as 'tenants in common' - that way neither side could sell up and leave the other homeless.

Making sure both you and they are protected shouldn't be controversial, unless they're aiming to do something underhand. I hope you can get the right advice and organise things so that you are all happy.

It sounds like a neccessity ! get a good solicitor to draw it up and make it legal , if they are paying you rent it needs to be in writing even if it is peppercorn
