房客不付房租, 準備上法庭. 有關條文看不懂, 請幫忙

我們在TEXAS, FRISCO有一個townhouse, 出租一townhouse給一對老美夫婦, 對方自去年九月起拖欠房租, 總是到月底或下月才付, 水電費也是到電力公司要斷電的那一刻才把非付不可的部分, 其他部分還是欠著.
至今還沒有付三月份和四月份超過的房租, 水電費已經欠了超過$800(從12月起).
我們要去法院申請驅逐令. 今天看TEXAS法律, 有如下規定,
(d). Waiver of Default

Either party can waive the right to terminate, by accepting late or substandard performance. Harris, 93 S.W.2d at 600. Once is waived, the party cannot begin to insist on strict performance again until notice of such insistence is given. Cox's Bakeries of North Dakota v. Homart Develop. Corp., 515 S.W.2d 326, 329 (Tex. Civ. App.--Dallas 1974, no writ). But see Taherzaikh v. Clements, 781 F.2d 1093 (5th Cir. 1986). For example, once a landlord accepts late payments, the landlord cannot claim a tenant is in default and attempt to evict the tenant for another late payment, until the landlord gives the tenant advance notice that future late payments will be considered a default under the lease.
請幫忙看看上麵是不是說如果我們曾經接受過遲付的房租, 我們就放棄驅逐房客的權利了呢, 即使以後不付房租, 我們也得先發通知, 多少天以後才能申請驅逐?
另外關於電費, 電費帳單在我們的名下, 以前我們把帳單傳給他們, 由房客直接付給電力公司. 現在他們欠費太多, 我們不敢隨便斷電,怕違反法律規定.
