To determine whether you are legally competent, a doctor will check whether you understand the options available. Whether you understand that is evident from:

• Whether you can make a clear choice yourself and convey it well
• Whether you understand the information about e.g. the treatment or illness
• Or you realize what the information means for your situation
• Whether you can properly weigh up the options based on the information you have received

For example, the doctor may ask questions such as: "Can you tell in your own words what you want to arrange and why?"

Whether you can decide independently also depends on the type of decision. Especially in the case of a radical treatment, it is important that you understand what the consequences and risks can be.
