Lawyer or notary in Zürich - last will

Hi all,

I would like to create a last will (I'm healthy, just a bit afraid of some upcoming sports events that I will attend) and for that, I'm looking for a lawyer or, if it's "enough", a notary.

Background: we have a family (my spouse and kids), and as the kids are all U18, I would like my partner to inherit everything, if something happens to me, this way, it would be much easier for her to be on top of things after the terrible loss (me), and it won't be the guardian who is handling everything until my kids turn 18.

I searched this thread for similar subs, couldn't find what I was looking for. I also asked my friends, it seems family matters nowadays are about divorce, I'm looking for something simpler.

Thank you in advance!
