My uncle passed away can I use his Tallit?
Regarding using your late uncles tallit, since your uncle passed away, the tallit now belongs to his heirs, meaning the people who inherit him or if he made a kosher will and willed it to them. therefore you have to ask them if you can use it. This will apply only regarding using the tallit on a permanent basis, however if you want to merely use it in a one time basis, you may, because we can readily assume that the owner would want you to do a mitzva with his object. However, you have to remember to fold it up and return it the same way that you received it.
Regarding the fact that it is the tallis of a deceased person, it is permitted to use the items of a deceased person, but not his shoes.
