What can I do if I have a motion to strike hearing and I can’t afford an attorney?

If you cannot find legal counsel, you will need to review the Michigan Court Rules on "motion practice". I don't know what a motion to strike hearing is. If you are in pro se (without a lawyer) and you can't make it to a hearing, contact the other attorney and ask for an adjournment. If he or she is a jerk, file a motion to adjourn, notice of hearing and proof of service and ask for the adjournment. Nobody can "afford" a lawyer anymore you can afford to get cancer or heart disease. The issue is you probably have to decide your future is worth enough that you need to hire an attorney. I would suggest you try to obtain legal counsel.
