Insurance application details with marital status error

I have a child without marriage certificate.

When filling out the insurance form for medical & life insurance for me, the agent thought I'm married so he put my marital status as "Married".
The pricing of the insurance is the same for married & non-married.
The policy is 2 years old.

My questions are,
1) could the insurance company void my policy?
2) could they reject my claims in the future?
3) is this a fraud? (since I do not benefit from declaring married or non-married)
4) if my marriage certificate date is later than the policy application date (I get married afterward), could they still void the policy or reject my future claims?
5) what do you suggest I do? Terminate the policy and apply new one with valid information?
