Thanks for your enquiry.
The only potential saving you would be making by having the Deeds transferred into your joint names is if your Mother were ever to go into a Nursing Home. If this ever happened and she owned th eproperty in her sole name, then th ewhole value of the property would be classed as her capital when calculating whether she would benefit from state assistance with the N Home fees.
If she owned only half of the property, then only half the value of the property would be used in th eabove calculation.
However, if the state can show that someone has deliberately given away assets (ie half of th ehouse) to avoid payment of Nursing Home fees, they can still trat that person as owning what they have gifted away, when calculating their eligibility for state assistance.
To get round this problem, your Mother could instruct a local Wills Solicitor to prepare a "Deed of Variation" to your Father's Estate whereby his half share of the property passes to you. This can be done post death but only if th eproperty was of course in their joint names.
If your Mother does proceed with transferring half to you, she would be made aware of the folowing-
1. She loses legal ownership of half of the property, and would be reliant on you agreeing to sell and using the full proceeds if she ever wanted to downsize.
2. If you were to die before her, your half share passes in accordance with your Will, or if you had not made a Will, to your next of kin who would be your Wife, if you were married.
3. If you get divorced/made bankrupt, the property may have to be sold in order to pay a third party!
4. If you own another property, you would be liable for Capital Gains Tax on any profit you make when th edate you acquire your half share and the date the property is eventually sold.
So, there are quite a few factors to consider, and if your Mother is not too concerned over the Nursing home scenario, it would be better to leave things as they are.
I hope this sets out the legal position to you.
