My ex husband is now using drugs and not helping pay the extra things we had agreed upon outside of court can I reopen?

You can reopen the case if you can show that there was fraud on his part and you relied on it and were damaged.

You should have a family law attorney review the Judgment of Divorce which will provide information necessary to answer your question. As a general rule, if the Judgment of Divorce states that alimony is being awarded and is forever barred, it cannot be re-opened later. An exception to this rule would be if there was fraud, etc. in the inducement to not seek alimony. The fact that you elected to handle some items outside the Judgment will not be grounds to now re-open it. Again, you should seek legal advise from an attorney.

Depending on the provisions of the Judgement, certain issues may be reopened. You should consult with an attorney and review your Judgement of Divorce and determine what issues can be raised in court.

In the State of Washington, it is very difficult to reopen a finalized divorce for the purpose of changing the financial terms of the divorce; it typically requires strong evidence of a party's fraudulent material misrepresentations to the court. If the reason that no spousal maintenance was ordered was principally based upon the alleged inability of the husband to pay, and the supposed wage discrepancy was very significant, then it might be possible able to have the court reopen the case, but there are time limits to doing so. You need to discuss your particular situation and facts with an attorney to determine if there is any basis for doing so at this time. A divorce does not need to be reopened if there is a real safety issue regarding the children that might justify modifying the parenting plan, or the child support needs to be modified due to the substantial income discrepancy. There are legal parameters that determine when the court can consider making modifications; again, an attorney would be able to assist you in this matter.

If there has been a material and substantial change of circumstances, orders (including child support) can be changed. I suggest you hire a lawyer.
