Insurance Code (usually included in commercial codals)
Section 50. The policy shall be in printed form which may contain blank spaces; and any word, phrase, clause, mark, sign, symbol, signature, number, or word necessary to complete the contract of insurance shall be written on the blank spaces provided therein.
Any rider, clause, warranty or endorsement purporting to be part of the contract of insurance and which is pasted or attached to said policy is not binding on the insured, unless the descriptive title or name of the rider, clause, warranty or endorsement is also mentioned and written on the blank spaces provided in the policy.
Unless applied for by the insured or owner, any rider, clause, warranty or endorsement issued after the original policy shall be countersigned by the insured or owner, which countersignature shall be taken as his agreement to the contents of such rider, clause, warranty or endorsement.
Group insurance and group annuity policies, however, may be typewritten and need not be in printed form.
