DH's grandmother has to move into a care home as she is no longer able to live at home due to health and care needs. As a result we now need to empty her rental bungalow as it needs to be returned to the landlord. Moving her stuff out isn't the problem, she moved into the bungalow after the death of DH's grandfather and all the mass decluttering happened when she sold the house to move closer to us all. The main problem is that she has a garage full of the taxi drivers belongings.
This taxi driver befriended his grandmother when she first moved to the area, she has many complex health needs which required her to go to the local hospital for management on a regular basis. DHs grandmother is low contact with both her children (FIL, aunt and uncle) due to MH issues. Until she deteriorated she was fiercely independent and would take a taxi to all her appointment's. It is a small local firm with only a few drivers and as she often booked in advance would request the same driver. At some point he needed to store some furniture and Grandmother offered use of her garage (we only found out when BIL went into the garage on one of his visits and found it full of furniture). He never paid her for this storage and over the years he has put more and more items in the garage, using it like a storage unit come garden shed. The entire garage is full and piled high with all sorts of furniture, knick knacks, garden equipment, etc.
BIL has phoned the taxi driver multiple times to collect his belongings which he is storing in GP's garage as GP needs to move into care and will be giving up her bungalow and it needs to be returned empty. However the taxi driver is now refusing to collect them and says he has nowhere to put it all or anything to collect it with. This means we either have to pay to dispose of it or pay to store it all for him (which we are not doing).
I have suggested we send him a written letter saying if items are not collected by X date they will be disposed of/ sold/ donated.
WIBU to put all the items on Facebook marketplace, Freecycle, gumtree and donate the rest? All of the items in the garage are of good quality and in working order.
