Can The Price Increase?

Can the surrogate ask for more money after she is already pregnant? Can the doctors ask for more money before the delivery?

The answer is yes.

With Delivering Dreams, all costs except those mentioned above, are fixed and your contract is under US law. The surrogate cannot ask for more, nor can the clinic or maternity hospital.
In working with local companies, anything is hypothetically possible. Contracts will be under Ukrainian law and the presiding language will be Ukrainian. One of my greatest concerns is that if you do face a demand for additional or higher payments, it is hard to find any recourse and impossible, of course, to walk away.

Surrogacy in Ukraine is highly regulated. However, neither agencies in Ukraine nor contracts between parents and clinics or agencies are regulated. This is an important distinction to understand. This is one of the reasons our contract is signed and governed by US law.
