Lets assume you do leave things as they are.
Depending on the value of your property, there could be an inheritance tax liability to pay on second death. So, I think it is worth while that you telephone a solicitor with the approximate value of your assets to see if it is necessary to take action to mitigate this possible liability. We took this action recently, and for a few hundred pounds in legal fees, we should save our beneficiaries many thousands in inheritance tax ( if the present tax law is still in place)
