1520.What is the time limit for filing evidence of one-half support?

In order to establish potential entitlement to benefits on the insured worker's Social Security record, parents must file evidence of one-half support within the two-year time limit. The two-year period within which the evidence of support must be filed depends upon the circumstances. (See 423.)

We may extend the time if good cause, as explained in 1519, is established for failure to file the evidence within the time limit.
