The legal rules apply to landlords and tenants in rice lands under Act No. 4054, as amended by Commonwealth Act No. 178.
The rules govern tenancy contracts between contracting parties and the resulting rights and obligations for landlord-tenant relations on rice lands.

Section 7 governs rules governing tenancy contracts in any tenancy contract mentioned in Act No. 4054.
Contracting parties are free to enter into any or all kinds of agreements or stipulations in tenancy contracts.
Freedom to contract is limited to stipulations not contrary to existing laws, customs, morals and public policy.
A tenancy contract is conclusive evidence of what has been agreed upon between the contracting parties.
