Paying into husband's house

[AlmostAlwyn]

We currently live in a house which is owned my my MIL, which my husband will inherit (or she will transfer ownership to him) at some point. It needs quite a lot of work done on it. We have a joint account, but I have £6000 in a separate savings account. My husband is suggesting using my savings (as a contribution as it will cost more), saying it's an "investment".

Obviously, it is. It's my home too, but am I right not to be sure about it? If the money gets used, then I'm not sure I'll start another separate savings account. Also, what would happen in the event of a divorce? If nothing was written down, I guess I wouldn't get that money back...?

AIBU to say no, we're not using my savings?

The husband does not want to use the joint account money. He wants to use her money.

He likes other women to pay for things for him, doesn't he?

There are no other siblings to object to the way things stand to be inherited. Unlikely that MIL will go crazy and leave the house to a cat shelter, but... well, I already said you never know

"He likes other women to pay for things for him, doesn't he?" No, that's not the case at all.

I realise we've been benefitting from living here rent free, but we both have, so I don't think just my money should be used.

Anyway, I had a chat with DH and he agreed that we wouldn't use my savings if I didn't want to. I'll see how it goes and perhaps reconsider if things change in the future!
