什么是主債權

主(zhu)債(zhai)權是抵押權所擔(dan)保的(de)(de)原本債(zhai)權，是依當事人之間的(de)(de)主(zhu)合同產生的(de)(de)不包括約(yue)定利息、違約(yue)金(jin)、損(sun)害賠償金(jin)在內的(de)(de)最開始的(de)(de)債(zhai)權。抵押權從產生到消滅，都是為了使主(zhu)債(zhai)權得以(yi)圓(yuan)滿實現，所以(yi)主(zhu)債(zhai)權毫(hao)無疑問(wen)屬于抵押擔(dan)保的(de)(de)范圍。

無論被擔(dan)(dan)保(bao)的(de)債權(quan)(quan)屬于何種類(lei)債權(quan)(quan)，一(yi)般來說，當事人在(zai)抵(di)(di)押合同中都應就被擔(dan)(dan)保(bao)的(de)主(zhu)債權(quan)(quan)的(de)種類(lei)、數額作出約定(ding)并在(zai)抵(di)(di)押權(quan)(quan)設定(ding)登(deng)記(ji)時一(yi)并加以(yi)登(deng)記(ji)。這是(shi)出于抵(di)(di)押權(quan)(quan)特定(ding)原則(ze)的(de)需要。因為如果主(zhu)債權(quan)(quan)的(de)種類(lei)數額沒(mei)有確(que)(que)定(ding)下來的(de)話(hua)，抵(di)(di)押權(quan)(quan)人可以(yi)支(zhi)配(pei)的(de)抵(di)(di)押物交(jiao)換(huan)價(jia)值就無法確(que)(que)定(ding)；抵(di)(di)押權(quan)(quan)得(de)以(yi)優(you)先受償的(de)范圍也就沒(mei)有確(que)(que)定(ding)。

主債權合同是什么

根據現行相關法律規定，主(zhu)債(zhai)(zhai)權(quan)(quan)是相(xiang)對于債(zhai)(zhai)權(quan)(quan)中附隨債(zhai)(zhai)權(quan)(quan)而言的，比如(ru)說擔保債(zhai)(zhai)權(quan)(quan)。債(zhai)(zhai)權(quan)(quan)的履行(xing)(xing)(xing)期(qi)間是指應當在(zai)某個時(shi)間段內(nei)(即期(qi)間)履行(xing)(xing)(xing)的債(zhai)(zhai)權(quan)(quan)。舉(ju)個例子，你去銀行(xing)(xing)(xing)貸(dai)款(kuan)，你需(xu)要以房屋做(zuo)為(wei)抵押(ya)，那么與銀行(xing)(xing)(xing)的貸(dai)款(kuan)合(he)同是主(zhu)合(he)同，而房屋抵押(ya)合(he)同就是為(wei)了保證銀行(xing)(xing)(xing)債(zhai)(zhai)權(quan)(quan)的實現而存在(zai)的抵押(ya)合(he)同。

主債(zhai)權(quan)(quan)(quan)(quan)人在(zai)依法(fa)將其(qi)債(zhai)權(quan)(quan)(quan)(quan)轉讓(rang)給第三人后，受(shou)讓(rang)人就(jiu)有(you)權(quan)(quan)(quan)(quan)在(zai)主債(zhai)務(wu)人不(bu)履行(xing)(xing)(xing)(xing)債(zhai)務(wu)的情況(kuang)下要(yao)求(qiu)銀(yin)行(xing)(xing)(xing)(xing)承擔(dan)保(bao)證(zheng)責(ze)(ze)任，銀(yin)行(xing)(xing)(xing)(xing)不(bu)能無故(gu)拒絕。但需要(yao)明(ming)確的是(shi)，擔(dan)保(bao)銀(yin)行(xing)(xing)(xing)(xing)只(zhi)在(zai)原(yuan)范圍內承擔(dan)保(bao)證(zheng)責(ze)(ze)任。如(ru)果債(zhai)權(quan)(quan)(quan)(quan)人在(zai)轉讓(rang)主債(zhai)權(quan)(quan)(quan)(quan)時(shi)擴張了主債(zhai)權(quan)(quan)(quan)(quan)及其(qi)從屬(shu)權(quan)(quan)(quan)(quan)利(li)（比如(ru)未付利(li)息請(qing)求(qiu)權(quan)(quan)(quan)(quan)、違約(yue)金請(qing)求(qiu)權(quan)(quan)(quan)(quan)、損害賠償請(qing)求(qiu)權(quan)(quan)(quan)(quan)等等），擔(dan)保(bao)銀(yin)行(xing)(xing)(xing)(xing)對(dui)擴張部(bu)分(fen)的債(zhai)權(quan)(quan)(quan)(quan)自(zi)然不(bu)用承擔(dan)保(bao)證(zheng)責(ze)(ze)任。當然，銀(yin)行(xing)(xing)(xing)(xing)也不(bu)能乘機出爾反爾，企圖縮(suo)小或免(mian)除其(qi)原(yuan)保(bao)證(zheng)責(ze)(ze)任。

總而言之，主債權合同就是指在簽訂因同一事項衍生的多個合同中，占據主要債權的合同，這個合同規定的權利和義務同樣也約束著其它合同的行使。而具體什么樣的合同是主債權合同，根據具體的合同簽訂情況，再具體界定。

主債權的種類有哪些

主(zhu)債權(quan)種類(lei)包括(kuo)有名(ming)合(he)(he)同(tong)(tong)(tong)，合(he)(he)法(fa)有效的無名(ming)合(he)(he)同(tong)(tong)(tong)。債權(quan)因(yin)合(he)(he)同(tong)(tong)(tong)、無因(yin)管理(li)、不(bu)當(dang)得利、侵權(quan)行為(wei)四種原因(yin)而產生。有名(ming)合(he)(he)同(tong)(tong)(tong)主(zhu)要有：買賣合(he)(he)同(tong)(tong)(tong)、供用電、水、氣(qi)熱(re)力合(he)(he)同(tong)(tong)(tong)、贈(zeng)與合(he)(he)同(tong)(tong)(tong)、借款合(he)(he)同(tong)(tong)(tong)、租賃(lin)合(he)(he)同(tong)(tong)(tong)、融資租賃(lin)合(he)(he)同(tong)(tong)(tong)、承攬合(he)(he)同(tong)(tong)(tong)、建(jian)設工(gong)程合(he)(he)同(tong)(tong)(tong)、運輸合(he)(he)同(tong)(tong)(tong)、技術合(he)(he)同(tong)(tong)(tong)、保管合(he)(he)同(tong)(tong)(tong)、倉儲合(he)(he)同(tong)(tong)(tong)、委托(tuo)合(he)(he)同(tong)(tong)(tong)、行紀合(he)(he)同(tong)(tong)(tong)、居(ju)間合(he)(he)同(tong)(tong)(tong)。

主債權人債權轉讓是怎樣的

1、主債權(quan)的轉讓必(bi)須(xu)是在保證(zheng)期(qi)間(jian)內發生的

保(bao)(bao)(bao)證(zheng)(zheng)(zheng)期(qi)間(jian)是擔保(bao)(bao)(bao)銀(yin)(yin)(yin)行(xing)承擔保(bao)(bao)(bao)證(zheng)(zheng)(zheng)責(ze)任的(de)時(shi)限。根據《擔保(bao)(bao)(bao)法》第(di)(di)25條的(de)規定，在保(bao)(bao)(bao)證(zheng)(zheng)(zheng)期(qi)間(jian)內，主債(zhai)(zhai)權(quan)人(ren)(ren)未對(dui)債(zhai)(zhai)務人(ren)(ren)提起訴訟或仲裁，保(bao)(bao)(bao)證(zheng)(zheng)(zheng)人(ren)(ren)免(mian)除保(bao)(bao)(bao)證(zheng)(zheng)(zheng)責(ze)任。換言(yan)之，銀(yin)(yin)(yin)行(xing)的(de)保(bao)(bao)(bao)證(zheng)(zheng)(zheng)責(ze)任隨(sui)著保(bao)(bao)(bao)證(zheng)(zheng)(zheng)期(qi)間(jian)的(de)屆(jie)滿而消(xiao)滅，在保(bao)(bao)(bao)證(zheng)(zheng)(zheng)期(qi)間(jian)屆(jie)滿之后，主債(zhai)(zhai)權(quan)人(ren)(ren)將(jiang)其債(zhai)(zhai)權(quan)轉讓給第(di)(di)三(san)人(ren)(ren)，就(jiu)與擔保(bao)(bao)(bao)銀(yin)(yin)(yin)行(xing)毫無關系了。

2、主債權的轉讓必須依法或依約作出(chu)

首先，須有合法(fa)有效的主債權存在，這(zhe)是(shi)主債權轉讓的基本前(qian)提。

其次，主(zhu)債(zhai)權(quan)須有(you)可(ke)轉讓(rang)(rang)性(xing)，依據債(zhai)權(quan)的(de)性(xing)質（如(ru)以(yi)特定(ding)身份為基礎的(de)債(zhai)權(quan)或基于原(yuan)債(zhai)權(quan)人與(yu)債(zhai)務(wu)人之間(jian)特殊信任關系的(de)債(zhai)權(quan)）或原(yuan)合同當(dang)事人的(de)約定(ding)不得轉讓(rang)(rang)的(de)債(zhai)權(quan)不能轉讓(rang)(rang)。

再(zai)次，主債權(quan)(quan)人與第三人達成了轉讓債權(quan)(quan)的書(shu)面協議。

最后，主(zhu)(zhu)債(zhai)(zhai)權(quan)的轉讓不(bu)得(de)違反(fan)主(zhu)(zhu)合同(tong)(tong)(tong)或(huo)(huo)保(bao)證合同(tong)(tong)(tong)的約定(ding)，比如主(zhu)(zhu)合同(tong)(tong)(tong)約定(ding)，債(zhai)(zhai)權(quan)轉讓須(xu)經(jing)過(guo)主(zhu)(zhu)債(zhai)(zhai)務人(ren)(ren)的同(tong)(tong)(tong)意而實際上主(zhu)(zhu)債(zhai)(zhai)權(quan)人(ren)(ren)轉讓主(zhu)(zhu)債(zhai)(zhai)權(quan)時未經(jing)主(zhu)(zhu)債(zhai)(zhai)務人(ren)(ren)的同(tong)(tong)(tong)意，而主(zhu)(zhu)債(zhai)(zhai)務人(ren)(ren)又未加以追認，或(huo)(huo)者主(zhu)(zhu)債(zhai)(zhai)權(quan)人(ren)(ren)與(yu)擔保(bao)銀(yin)行在保(bao)函中約定(ding)，主(zhu)(zhu)債(zhai)(zhai)權(quan)的轉讓必須(xu)經(jing)銀(yin)行的同(tong)(tong)(tong)意，但(dan)主(zhu)(zhu)債(zhai)(zhai)權(quan)人(ren)(ren)轉讓債(zhai)(zhai)權(quan)時卻(que)未征得(de)銀(yin)行同(tong)(tong)(tong)意，銀(yin)行又拒絕追認。

在上(shang)述情(qing)形下，主債(zhai)權的(de)轉讓對擔保銀行就鞭長莫及(ji)了。

三(san)、主債權人應將(jiang)債權轉讓通知主債務(wu)人

一般來說，債權轉讓無需征得債務人的同意，但主債權人應將債權轉讓通知債務人，并且債權轉讓不得增加債務人的負擔。債權轉讓自債務人得到通知之時起對債務人發生法律效力。債權轉讓只有對債務人(ren)發生法律(lv)效力之后才能影響到擔保銀行的責任承擔。
