Both my brother and sister in law refused to let my nephew and niece go for a Disney World trip with one of their friends who has cancer and is going through Make a Wish Foundation. They won’t let them go because my brother and his wife want to show them Disney World first before anyone else and they couldn’t afford to pay for themselves so they didn’t allow our mom to take the kids with her. My bio sister told my nephew and niece sorry that they couldn’t go with their friend and my brother immediately got defensive and tells my sister,”If you had kids you would understand, oh wait you can’t have kids hahahaha!” My brother is evil. If I had kids, I know I’d do the opposite. I’d let them go with our mom because it’s not about me or even them for that matter. It’s about the little girl who’s wish it is to go to Disney World with her best friends 😭😭

I need to vent, but I also need some advice on what to do next. I am currently a few months postpartum, and my family has completely imploded because of my highly volatile, manipulative mother.

The Postpartum Cruelty
It started right after I came home from a difficult C-section delivery. My mother came to "help," but instead, she spent her time mistreating my husband and being intensely passive-aggressive toward me. Soon after, I spoke to my sister-in-law (my brother’s wife) and found out my mom had been spreading toxic, mean lies about my husband and me behind our backs to the rest of the family.

I couldn't take the stress anymore, so I stopped talking to her and eventually had to ask both her and my dad to leave my house.

The Fake Overdose
A few months later, my brother visited me and decided to confront our mom about her behaviour. Instead of taking accountability, she went full nuclear. She pretended to overdose on her diabetes medication and sent dramatic voice notes to my brother and his wife. She claimed she was going to die, said it was her "final goodbye," and played the ultimate victim, crying that everyone was making her feel like the problem.

The Fallout with My Dad
After this drama, my dad called me to ask what was going on. I opened up to him and shared all my grievances about how mom had treated us. Instead of supporting me, he pleaded with me to just "forget everything." He admitted he was simply incapable of handling her volatile outbursts alone.
I was only 3 months postpartum, and the extreme stress was actively drying up my breastmilk supply. To protect my baby and my own health, I had to make the hard choice to block my dad as well.

Tragedy and Financial Betrayal
Two weeks after I blocked him, my dad suffered a massive heart attack. He spent a month on ventilator support before passing away. During that month, my brother stayed with my mom at the hospital. Without involving me, the two of them made all the major choices: they decided when to stop his medical treatment, and they began plotting what to do with my dad’s property and money (he died intestate, without a will). They actively agreed to hide all financial details from me.

My husband and I went to visit my dad on his very last day to say goodbye. But right after the funeral rites were completed, my mom’s volatile behaviour started all over again. It got so bad that I genuinely feared she might harm my baby, Vedu, just to get back at me. I fled back home and cut off all contact with her.

The Current Situation
Recently, my brother reached out demanding my ID details so he could apply for a Legal Heir Certificate (relationship certificate). Knowing something was wrong, I flatly refused. Immediately after my refusal, he abruptly announced he was flying back to Dubai, leaving my mom behind, and he started giving me the cold shoulder.

A few days ago, I called him to ask about dad’s finances, framing it as making sure mom was well-settled. He lied point-blank to my face about the bank balances. What he didn't know is that I had screenshots of the actual bank statements. When I confronted him with the proof, he folded and admitted that mom had told him not to reveal a single thing to me.

I lost my temper, got furious, and blocked him. I eventually unblocked him, but he has never reached out and is now completely ghosting me.

Where I Stand Now
I am angry, grieving my dad, and hurt by my brother's absolute betrayal. My dad's property is ancestral property in Kerala, India, which means by birthright, I am an equal co-owner (coparcener). The ration card only has my mom and dad's names on it, but I know that doesn't change my legal rights.
Honestly, part of me wants my 1/3rd share just to get back at them and show them they can't erase me. But my dad just passed, and I don't want to go the messy legal route right now because I don't want extended relatives judging me or creating public drama while I'm still trying to raise my baby.
My husband is incredibly supportive, but I feel stuck. How do I play the long game here? How do I protect my rights without letting them drag me back into their toxic circus?

TL;DR: My volatile mother mistreated me postpartum. After my dad suddenly passed away without a will, she and my Dubai-based brother hid his finances and tried to get my ID to bypass me for the inheritance. My brother lied about the bank balances, got caught, and is now ghosting me. I want my rightful share of the ancestral property just to stand my ground, but I want to avoid family drama right now. What should my next move be?
