IN case of Hindu male;
His, sons/daughters/wife have NO forced share in his self earned/acquired estate/property.
Wife is not a Co-parcener in ancestral property of husband.
Hindu husband/father is liable to maintain;
his sons till they attain adulthood
daughters and marry them as per his resources.
Although spouse and children can allege DV, that may need to be established.
False allegations become ground for separation as; Cruelty.
The said brothers and relatives have NO reason or right to influence the father as in query to harass, abuse, beat the spouse, children.
The spouse and children can of course approach state/police for allged harassment, nuisance, undue influence and prove the allegations…
However IT shall be better to involve the elders of the family, well wishers, panchayat, community leaders, mediators to find amicable soloution to the issue and resolve the matter.
If required, state/police can be involved and matter can be on records, for future reference.
In the end IT is spouses, children that shall be affected by unnecessary altercations, family disputes and if shop is the only source of income then income from shop that is required to maintain the family may be gone.
IT is entirely family’s internal and private matter to change the location of shop and can be solved within four walls of the family or with outside help.
Hope you are clear after reading all posts and may act wisely.
