I am being sued for a breach of contract on a utility bill that does not involve a written contract. Service was signed up via telephone. The date of the last payment on the account has passed 2 years. I was served by substituted service at a residence I don't reside at. How can I file a demurrer to state the statue of limitations have expired? Also, I am aware of the lawsuit now, but I wasn't aware of the substituted service until 2 weeks after when I received a call from a family member who was able to finally reach me. Does this add any additional days to file a response from the date of substituted service rather than the 30 days on the document?
