In case of alzheimer's

For the past 16 months my wife has been living overseas in her home country. She is staying in a nursing home with advanced case of Alzheimer’s disease. How long do I have to wait before filing for divorce? Would this kind of divorce case be considered complicated and expensive?

You may file for divorce now and must have her served with the papers, the divorce portion of the process is fairly simple and will be final in about 60 days. If you have martial property together you will need to include a claim for equitable distribution to divide the martial property. If property distribution is not pending before the court at the time of the divorce the property goes to the title holder.
