Separation agreements must be originally made in accordance with local and national laws. Not every taxpayer is familiar with these laws to create the document on its own. This is why it is important to ask a professional to write down the document or use the already-made template. Once you find the template you need with all the aspects that must be included there, you can fill it. If you notice that there are several extra lines you want to add, you can do it in a separate attachment or ask the lawyer whether you can include it in the agreement.
