Questions & Answers about Ya he cambiado mi domicilio en el ayuntamiento porque me mudé el mes pasado.

Why does the sentence say ya he cambiado instead of ya cambié?

In Spain, he cambiado (the pretérito perfecto) is very commonly used for a past action that is seen as connected to the present or relevant now.

So Ya he cambiado mi domicilio suggests:

• the change has already been done
• the result matters now

The word ya reinforces the idea of already.

In much of Latin America, many speakers would more naturally say ya cambié mi domicilio. In Spain, ya he cambiado sounds very normal.

Why is it he cambiado in the first part, but me mudé in the second part?

This is a very common question, especially for learners of Spanish from Spain.

The difference is mainly about how the time is presented:

• Ya he cambiado mi domicilio
  No finished past time is stated here. The action is presented as relevant to the present.

• porque me mudé el mes pasado
  El mes pasado is a clearly finished past time period, so Spanish from Spain normally uses the pretérito indefinido: me mudé.

This contrast is very typical in Peninsular Spanish:

• Este mes he trabajado mucho.
• El mes pasado trabajé mucho.

So the sentence mixes the two tenses for a good reason.
