I don’t know, but if she was baptised wouldn’t the fact that it was a Hindu ceremony mean their marriage wasn’t valid anyway?

Can you ask your father about her or talk to her and ask these questions?

I never studied hinduism anyways, so I don't know what they do. Isn't their god an 8 armed demon?

I don’t know and I don’t want to know. I don’t want to study the details about a demon worshiping religion. But it wasn’t a catholic ceremony

I'm not telling you to "study"  the demon worshipping religion. I'm saying ask your dad if she was born into hinduism or became one later in life. Like I would tell people to STUDY the details...

My dad was an ex Hindu, that’s why he did the Hindu ceremony, not because of her

Anyawys, I'm not calling you a bastard, because your issue is confusing right now, but bastards cannot become priests.

Is this the first time you said he's an ex hindu? Because I didn't see you mention this before. I read-"well my dad was novus ordo before he apostatized..."  and  "He was first "married" in a hindu ceremony as a baptised Catholic..." 

So, I figured it was all demon hindu stuff because of the woman. Why didn't you make that clear from the starting post?  I took it that your father was "a novus ordo before he apostatized" because that's what you said.

my bad 

Can there be a dispension?

also if the first “marriage” is invalid is the “second” also invalid

Do you talk to your father about this? Are both your parents Catholic, like SSPX? Where do you attend Mass, SSPX? I would talk to a priest at my SSPX parish about these issues. They just need to prove that your dad or his ex-first "wife" weren't BAPTIZED, this is the most important issue, because Christ Almighty did not recognize it. Say the first issue is all situated & there was no marriage, your parents' marriage is valid if both of them were validly BAPTIZED. Please go talk to a valid priest about this.
