I would advise very strongly against giving any ground on ownership of the property. You have no idea what might happen if they decide to leave their share of it somewhere else in their will.
You are the sole owner of the property – and I would keep it that way because anything else will start to introduce further complications and ambiguities – and at the end of the day the only beneficiary will be the solicitor. Imagine if your parents became part owners and then continued in litigation against you and started incurring costs which they were unable to satisfy – the next thing that will happen will be that the solicitor start to take action against the property as being your parents only asset and you will then be fighting possession proceedings brought by the solicitor to pay off his feet.
