Who hired the attorney? Seems that if the executor wishes, he can fire the attorney, and hire what he feels is a probate attorney with more experiance in that field.Not with so close ties, it might cloud his judgement. Just a suggestion.
I have successfully recommended Bill Parkas to my clients at McCoyd, Parkas & Ronan LLP, Garden City.
They are a medium sized firm specializing in estate work.
His email is firstname.lastname@example.org. Phone 516-877-7000
Your mother must hire a different estate attorney to represent her as using the estate's attorney is a conflict of interest. That attorney may have his own reasons for stalling especially if he was in charge of the business affairs of the deceased. That seems like a very long time to file probate but maybe it's being done to confuse possible heirs (some who may not have not been contacted) who might contest the will..I say this only because this was done to me years ago; the estate never contacted me even though I was a first degree relative and even though I hired an attorney (out of the phone book) to stay on top of the probate filling, they never told me the probate had been filed until months after and then only notified me by mail and sent it to the wrong address....It was too late to contest it by then..
