No. Merely filing for divorce is not an admission of fault by the petitioner.
That stated, there is nothing that prevents a divorce petitioner from admitting fault in his/her petition for divorce, but it is certainly not required to admit fault and merely filing for divorce is not any kind of automatic admission of fault by the petitioner.
If you are afraid that merely filing for divorce is constitutes an admission of marital fault on your part, do not be afraid; merely filing for divorce is constitutes an admission of marital fault on your part.
