Is it okay to write/enforce "Parent(s)" instead of "Parent" and or "Parents", with the s in paren, to show you/I do not know if one or two parents?

Options:

A) Parent(s)

B) Parents

C) Parent

I think the question title is my entire question, I do not mean to be rude just clear (just I am being pretty powerfully judged/moderated/corrected for using the "Parent(s)" spelling), is that enough explanation?

I am bothered/liable if I say Parent because that implies one parent or a single parent, while Parents can make it seem/sound like it was both parents involved, whilst Parent(s) meaning either parent/parents equally gives the veneer of the only grammatical security and objectivity I can speak for explicitly.

Speaking with your voice, you might seem to have to specify a full sentence to explain and describe clearly and unequivocally what you mean, but with text I thought there could be greater security (and necessary brevity).

For legal reasons, I do not want to describe which parent or if both parents were involved. Besides, I wish to not explain a full sentence (often repeating that I am not specifying which parent to be clear again, to not let people misread me) every time, while still accounting to use my "200 character count" letters wisely which can be an extremely serious factor, though not as costly as telling you which parent(s) I mean.

Is this/that a grammar err legal question? I want to make clear I am not specifying, and that the parent(s) are unspecified, in grammatical number by wording with parenthesis to mean unspecified clearly, in writing.
