An elderly cousin died last year… she had 7 wills with several different solicitors dated over the past few decades. Took a while to sort it all out.
What was annoying and avoidable was she kept asking a solicitor to come to see her in the nursing home and she’d get her/him to draw up a new will and get staff to witness it. Then do the same a year later, on 4 occasions same staff, including the home manager, now she seemed to be fully clued in and alert. And it’s her right to do this. And each of the solicitors accepted a fee and each will as properly drawn up.
Sorting it all out incurred more costs. The risk being of course that there was an 8th will knocking around. So all the local solicitors had to be contacted and asked to check. There is a surprisingly large number of local solicitors! And that was in a village in midlands, dunno how that works in a city.
And the final will was beyond messy, but it was legal. Left a mess for her heirs and the net effect looks likely to be another abandoned derelict house in rural Ireland and an ongoing battle between her siblings.
