What is the difference between a void marriage and a voidable marriage?

Question

I found out my spouse was already married when we got married, and I want to know whether our marriage is automatically void or whether I need to go to court. I have been reading conflicting things online and I would like to understand what Indian law actually says about this, which Act and Section applies, what the realistic timelines and costs are, and what I should be doing right now to protect my position. If the matter can be resolved without litigation I would prefer that route, but I want to know what my rights are before I agree to anything or sign any document.

What is the difference between a void marriage and a voidable marriage? is governed in India primarily by Hindu Marriage Act 1955, Section 11, Hindu Marriage Act 1955, Section 12 and Hindu Marriage Act 1955, Section 5. The short answer is set out below, followed by the practical steps most people in this situation need to take. Read it alongside the specific provisions named, because the exact relief available to you turns on the facts you can prove on paper.

Section 11 declares a marriage void ab initio, meaning it is treated as never having legally existed, if it contravenes the conditions in Section 5 relating to bigamy, prohibited degrees of relationship, or sapinda relationship without custom permitting it.

Section 12 lists grounds that make a marriage voidable, such as impotence, consent obtained by fraud or coercion, pre-marriage pregnancy by another person unknown to the husband, and mental incapacity, but these marriages remain valid until a decree of nullity is obtained.

A void marriage does not require a court decree to be treated as invalid, though parties often still obtain a formal declaration for clarity on issues like remarriage, inheritance and legitimacy of children.

Children born from void or voidable marriages are legitimate under Section 16 of the Hindu Marriage Act for the purpose of inheriting from their parents, even though the marriage itself has no legal standing between the spouses.

A petition for nullity of a voidable marriage under Section 12 must generally be filed within one year of discovering the fraud or force, or within a reasonable time after the marriage, depending on the specific ground invoked.

What to do next: 1) Identify whether your ground falls under the void categories in Section 11 or the voidable categories in Section 12; 2) Gather evidence supporting the specific defect in the marriage, such as proof of a prior subsisting marriage; 3) File a petition for a declaration of nullity in the family court promptly, especially for voidable marriage grounds; 4) Consult a lawyer to understand the effect on legitimacy of children and property rights.

If the other side has already issued a notice, filed a case or set a deadline, treat the matter as time-sensitive — most remedies under Hindu Marriage Act 1955, Section 11 carry limitation periods, and a delay you cannot explain weakens an otherwise strong case.
