How Legally Enforceable Is This Pre-nup?

Hi everyone, Location: Pennsylvania This isn't for me, but a family member. A week before the wedding, the groom surprised the bride (my family member) with a pre-nup. He supposedly had his dad's lawyer write it up, but we're not sure. It includes the following: 1. When/if she becomes pregnant, she must quit her job to become a stay at home mom. She cannot have a job while the child/children are residing in the home. 2. She cannot seek legal counsel outside of the marriage. I don't know if that means she has to use her husband's lawyer or just can't seek legal counsel at all, but it sounded like it was the latter. 3. She has no right to any stakes in his family's business. It's not a big business and she has no interest in that anyway. 4. In PA, when there's a divorce, there's an equitable distribution of assests. She must sign away her rights to this. 5. Should they divorce, she can only take her clothes and her dog and she is responsible for the debt for the house (the mortagage).

I think that's all of the demands. He did make her sign a document that she thought put her name on the deed/mortgage, but it didn't, it just made her responsible for the debt. Her name is not on the deed/mortgage. She was completely blindsided about this as were the rest of us. Another family member is taking the pre-nup to a lawyer on Monday. However, I just wanted to reach out and ask how enforceable is this? Is everything in the pre-nup legal?? We have all told her to not sign this. Any advice would be appreciated!

Edit: thank you all for the input! Please continue to post any advice you have! As of today (10/5/25) she has not signed the pre-nup and our family is telling her to not sign and to cancel the wedding; this is bascially a trap. Fingers crossed we get through to her ????????
