We could give a lot of legal answers to that question, and we do think the legalities are important. Taking care of matters such as estate administration or life insurance can help you move on in the future with the proper finances and peace of mind. However, we also know that someone who has just lost a romantic and life partner has to take some steps to deal with that loss.
An important thing for many people to do after losing a spouse is to ensure the time, space and ability to grieve is afforded. This involves letting your emotions run and evolve throughout the weeks and months following the loss. Yes, you do have to make some life decisions, but those necessary tasks don't have to be all you concentrate on during this time.
A second solid step following a major loss is seeking out a support system. Your support system might be comprised of family and friends that care about you. It might also include professionals who can take certain tasks off your shoulders so you can concentrate on healing.
Finally, anyone who has lost a spouse or other close relative should make sure to practice self-care. Get enough sleep, eat as healthy as possible and get some exercise. Many experts recommend avoiding overindulgence in items such as alcohol or food as a coping mechanism during this time if you can.
Depending on your circumstance, you might be juggling a lot of things at a time when emotions make it difficult to handle just one. One thing you can do is seek professional assistance with estate administration concerns, taking some legal and administrative tasks off your plate without sacrificing assets or your standing in any probate matters.
