mehar se buchne k leye talaq se munkar hywa ha

Assalam u Alikum

Mera question ye ha k meri sister ko mere behnoi ne talaq di more then 3 times.
Oor wo mehar se buchne k leye talaq se munkar hywa ha oor kehta ha k Court se khulla lo.
2 saal hone wale hen is me us ne 2 shadian b kr di mazeed aik ko b talaq di abi last wali us k ghar ha.
Is doran us ne hamri sister se b ni pocha shadion ka.
Ab jo gawa hen talaq k wo unki family k hen oor wo b apni family ki waja se gawai ni den geh.

Wo talaq se munkar ha pr 2 saal men koi jirga ni keya bulqeh hum se written men unko invite keye k aoo oor is musleh ko hull kro pr wo ye kehteh hen k Court ja kr khula lo ta k mehar na dena pareh.
Kindly advise
