Legally, divorce ends a valid marriage, creating a formal record and dividing assets, while an annulment declares the marriage never legally existed due to specific issues like fraud, bigamy, or incapacity at the time of the wedding, effectively erasing it as if it never happened and potentially impacting spousal support rights. Annulments require strict, specific grounds (like fraud or underage marriage) that prove invalidity from the start, unlike divorces, which often use no-fault grounds like "irreconcilable differences".
