Transfering property deeds....

:wave:
My MIL (who is on her own) is thinking of getting the house deeds changed so the house would then belong to my DH.
Her reasoning for this is, if she has to go into a home in the future she won't be made to sell the house to pay for it.

Is this a good enough/viable reason?
Are there any other reasons why changing the title deeds would be a good idea?
Are there any reasons why she shouldn't?


Any help much appreciated as she has been quoted £500 by a solicitor if she wants to do it. We're unsure whether her reasons are valid (as in if that could even happen)

Thanks :)
