My wife is collecting disability and I'm thinking of retirement next year when I file and start collecting SSI does she loose her disability check?
Hi. Assuming that what your wife collects is a Social Security disability benefit, then the answer is no. Your collecting benefits would have no adverse effect on your wife's benefits as long as she's receiving a Social Security benefit and not Supplemental Security Income (SSI).
By the way, if you're considering retirement you may want to strongly consider using our software (https://maximizemysocialsecurity.com/purchase) to fully analyze the options available to you in order to determine your best strategy for maximizing your benefits.
