If me and my tenant did not sign any tenancy contract, does that mean I can the police if the tenant jadi kaki busuk?

Of course there are receipts for paying the rent, but the word "rent" is never used. Just tenant name and the building name (no house number too mentioned too).

In that sense, does that mean I am free from the cycle of tenant can stays for months even if refuse pay rent cause I have to get a court order and instead I can call the police and accuse the tenant of staying in my property illegally?
