If they are relying on income from child support , then proof of funds must be submitted e.g. data about payer and information about their source of income.  

We have a 2 year old boy and are expecting another child.

@Chris Allen There is also some new legislation that will allow conversion of a 529 to a Roth IRA for the childs benefit  apparently without penalty (except taxes) which will be helpful if your kids don't have kids and don't use the 529.

This allows for each property to be placed as its own child  entity with its own protection.

Conversely, and what people frequently don't think about, is if something you or a child of yours causes an accident or similar situation puts you at liability, then a litigious plaintiff can bring a suit against you and all of your properties held in your name. 

Half a century ago, a child would have a roughly 50% chance of making it from 0 to 18 with married parents. 

The states are sending checks now, student loan forgiveness is massive...another $500 billion that impacts 37 million people, and the doubling of the child tax credit will surface again.Inflation was caused by massive stimulus, supply chain disruptions, going to war, not enough drilling, limited immigration for 1-2 years, 2-4 million extra early retirees, 2-3 million extra people on disability due to long covid, and 1 million more people passed away (some of which were workers). 

These days people have child support, large car payments, student loans, etc.

My wife and I just welcomed our first child recently and we are just loving this stage of our lives being parents and seeking to build financial freedom. 

I'm a non-practicing attorney (licensed in NY); I'm married with one child.
