With regards to not being able to afford legal advice, the first question I would ask you is: - Do you have legal cover on any insurance product?
If you do, a lot of these products actually cover more than just legal matters relating to your insurance. Give them a ring and check if you can get any advice from them as part of your cover.
The second question I would ask is, regardless of my previous point, can you afford not to take legal advice?
A firm I used to work for were very trigger happy with threats of taking ex-employees to court, including me when I left but was approached by an ex-client to deal with their affairs personally. I know of at least two other ex-employees who have been threatened with legal action and both of them took legal advice. The old company was effectively told to "stop playing silly buggers" and accept the fact that both the staff and the client's wanted to leave. Point to note, neither ex-employee approached the clients, the clients approached them direct and the ex-employees tried to do everything correctly by applying for professional clearance etc.
I work for a firm with a Wills and probate department, probate accredited with ICAEW, and we are currently swamped with probate work. I only joined them in early February and have spent almost my entire time working on probates. I have now worked on about 8 or so in that time and we have various others on the go from before my time.
It is something that we are actively looking to expand and we are even getting referrals from solicitors where the deceased was a client and we have a better understanding of their affairs.
Also, where we do the Wills, we give the clients the option to appoint us either as a primary or substitute Executor.
I also know of several other firms who provide this service, usually through a separate entity from the main accountancy practice.
