Becoming Joint Tenants with my son after a Deed of Variation

[TRS60]

I have recently varied my late husband's will so that this share of the house (50%) has been inherited by my son. My son has always lived with us due to ill health. I now wish for my son to become a joint tenant with myself via inheriting his father's share of the house. How do I achieve this change to the title deeds? I am currently the sole owner of the house. Will my son and I initially become tenants in common and then we'll have to change this to joint tenants or can we become joint tenants straight after the deed of variation on my late husband's will? Greatly appreciate details of the procedure required, many thanks in advance for your help.

I'm going to say that I am sure that this should be possible, but that you may do well to consult a good property solicitor. (Sorry, this wasn't my area when I was in practice).

If your son's long term illness makes him a vulnerable adult you should consult a solicitor that specialises in trusts.
Putting your share of the property into a special trust may be more IHT efficient than making you and your son joint tenants. Particularly if you intend to continue to live at the property and can't pay your son market rent.
