13th and 14th-century Saaremaa islanders married according to local customs. Marriage was monogamous in the Christian world, but there were also other forms of cohabitation alongside or instead of marriage in the 13th and 14th centuries.
The medieval peasant law of Saare-Lääne begins with a clause according to which a man who does not register his marriage in church within eight days (after getting married according to local customs?) must pay a fine of 50 marks. That was a very large amount for that time. Additionally, the law deals with divorce and the right of inheritance. For some reason, the clauses connected to inheritance and divorce are viewed in the law primarily by way of women, thereafter adding that the same applies to men.
13.–14. sajandi saarlased abiellusid kohalike tavade ja õiguse järgi. Kristlikus maailmas oli abielu monogaamne, kuid 13.–14. sajandil esines selle kõrval või asemel veel ka teisi kooseluvorme.
Saare–Lääne keskaegne talupojaõigus algab klausliga, mille kohaselt peab mees, kes kaheksa päeva jooksul (peale kohalike tavade järgi abiellumist?) abielu kirikus ei registreeri, maksma 50 marka trahvi. See oli oma aja kohta väga suur summa. Lisaks käsitleb seadus lahutust ning pärimisõigust. Pärimise ja lahutamisega seotud klauslid on seaduses vaadeldud miskipärast eeskätt naise kaudu, lisades seejärel, et sama kehtib mehe kohta.
