Witness signing a mortgage deed- who?

[WhoLurvesOrangeSoda]

I need to sign the mortgage deed for the house I'm purchasing.

Can I get my sisters partner to sign as a witness or is he classed as a family member?

They are not married, but do live together and have DC.

Thanks!

The guy at the post office did ours

Sorry forgot to answer, I think they'd be fine as you aren't family.

Thanks @CookPassBabtridge
Confused about who is actually classed as a relative in the world of law!

It shouldn't be anyone you are related to. Whilst not married your sisters partner shouldn't witness it, all you need is for a neighbour or friend to witness it.

Work colleague?

Remember, they are only witnessing g that you signed that name, nothing else. Any adult (apart from family) can do it.

Friendly people in a post office would be ideal, or a chemist They just need to know your name.

Wouldn’t go for your sister’s partner. Any non-related adult is fine - colleague, neighbour
