Change of title deeds

This 1's a bit tricky so any advise at all would be appreciated.

My stbx and I bought my mums local authority house 4 yr ago she gave us her discount so we got the house for a steal, the house was to be an investment for the 2 boys when my mum was no longer here. It is written into her will that when anything happens to her the house comes to me and him, couldn't put it in the boy's names as they were both under 18 at the time. The prat now wants his name on the title deeds obviously mum is not happy about this after all its been in her name for 50 yr. My sol says I have no option but to do it. Does anyone know what rights this gives him, my fear is that he will have landlord rights. He just couldn't wait until she wasn't here she's 76 the now. I suggested we put it into trust for the boy's oh no gready B doesn't want them having it now. Anyone come across something similar???????

Thanks for reading anyway.

I take it "you" being the daughter asked your mum to purchase the house at the discount price and she purchased it herself with your money under the "right to buy scheme". You lent her the cash, to buy it as her name had to be on the title deeds because of the "right to buy".

Im not a legal beagle so not sure if the rules are the same in Scotland as here but when I bought mine it states that ownership has to be retained for 3 years by the resident, so :-)is your mum a life time"trustee" of the house and you and X the "beneficiaries". If so then X does not have to be registered on the property, he will have to make a claim against the property to get his share of the value when its sold.
