Of course, and that's also how it was pre-Vatican II. Catholics are bound by church law. Protestants are not so bound. Read Ludwig Ott

I don't think I ever heard of Ludwig Ott, but in the RCC, every marriage is always presumed valid, schismatic or not. This novus ordo priest who stated they were not married is simply slinging empty and heretical slander.

Can. 1108 §1 Only those marriages are valid which are contracted in the presence of the local Ordinary or parish priest or of the priest or deacon delegated by either of them, who, in the presence of two witnesses, assists, in accordance however with the rules set out in the following canons, and without prejudice to the exceptions mentioned in cann. 144, 1112 §1, 1116 and 1127 §§2 - 3.

I don't think I ever heard of Ludwig Ott,

Prior to Vatican II, his books on moral theology were the standard used in most Catholic seminaries. Even today, most conservative and traditionalist seminaries (including schismatic SSPX and sedevacantist ones) use his works.

but in the RCC, every marriage is always presumed valid, schismatic or not. This novus ordo priest who stated they were not married is simply slinging empty and heretical slander.

When one party is Catholic, the marriage is only presumed valid if canonical form was followed. Additionally, the NOM priest has another good reason to assume the marriage invalid -- the Roman Rota, which is the Church's surpreme court in non-procedural matters, has already declared two marriages from this same traddy chapel to be invalid due to lack of form.

I have no idea what that means. A marriage is presumed valid until the facts which prove the invalidity of the bond are examined and brought forward, yes. Catholics who contract marriage before clergy without jurisdiction, without the appropriate dispensation, ipso facto contract an invalid marriage.

That's simply the law, and was the law long before Vatican II. Denying it doesn't change the matter.
