can you receive social security from an ex if you just file a dissolution

Whether you terminate your marriage through a divorce or a dissolution should not have any effect upon your rights to Social Security Benefits-- assuming you have rights or will have rights. If you are talking about  retirement benefits earned, through your spouse, and your right to payment equal to half of those, in certain circumstances, I believe you have to have been married for over ten years to that spouse.  You should check the Social Security Website or call your local Social Security office about how to qualify and how to remain qualified.  If you are talking about disability benefits, again, the use of a dissolution instead of  a divorce should make no difference. Again, talk with the people at Social Security to have them explain your rights to you and what rights you would lose, if any, upon termination of the marriage, as well as what rights you might lose if you marry someone else after this divorce or dissolution.
