Hi Elena. You might check with your local eviction guru on whether or not you can serve that notice yourself. If you are the property owner, you likely need to have someone else serve it for you and then fill out a proof of service. The key is to have her served properly and fill out the notice as well as the proof of service properly. You might call Todd Rothbard's office in San Jose. While he started his eviction-only practice in Silicon Valley, I think he might have an arm up your way now. He's also send you the forms and instructions for you need for free. I would not use anyone else to do an eviction in CA. In my almost 30 years in the real estate industry with a focus on PM I've served a ton of notices, but only had to send the file to Todd 5 times (both residential and commercial). Since I don't serve notices too often, I always check with him before I do to make sure I'm up to date. There is no charge to call his office and talk. You can drop my name, Katrina Edwards, Triumph Property Services if you like.
Again, the key is to fill out the forms correctly. You don't want your case thrown out on a technicality. Waste of time and money.
On the bright side, sometimes just serving the 3-day notice will get the tenant's attention and they fall in line.
Good luck to you.
