Typically a QDRO (Qualified Domestic Relations Order) would be issued allocating your spouse a share of the pension, should it ever enter pay status. These are complicated orders, although some employers offer standard QDRO's to use as a model, which are consistent with state laws and the needs of the pension administrator. Even lawyers often outsource the drafting of QDRO's to other lawyers or accountants who specialize in their preparation, so don't underestimate how tricky this can be.
