Personal Income Tax Advice in Spain

I am seeking a knowledgeable tax advisor with expertise in Spanish taxation to provide guidance regarding a specific transaction. I am a UK tax resident. I intend to sell my carried interest in a Central European private equity fund where I used to work to my adult daughter, who resides in Madrid. Additionally, I plan to extend her an interest-free loan to facilitate this transaction. It is important to understand the Spanish tax implications involved in this process. I will need insights on potential tax liabilities and compliance requirements associated with this arrangement. Additionally, I would like to have the advisor draft a very simple sale and purchase agreement and a loan agreement with my daughter in English and Spanish.
